THRE SHING-MA CHINE Specification of Letters Patent.

Patented March 28, 1909.

Application filed April 18, 1908. Serial No. 427,817.

vTo all whom it may concern:

, Collis, in the county o'll Traverse and State of Minnesota, have invented certain new and ues'ful Improvements in Threshing-ltlachines; and I do hereby declare the following to be a full, clear, and exact description ol' the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The primary object ol' this invention is to provide simple and highly-eiiicient means lor insuring the thorough separation oll grain from straw, chaff, etc., the straw being repeatedly agitated and turned over during the passage thereof through the machine.

The invention will be hereinafter fully set forth and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in perspective, with parts broken away. Fig. 2 is a transverse sectional view. F ig. 3 is a longitudinal sectional view. Figs. 4 and 5 are plan views of the two series of walking rakes. Fig. 6 is a detail view in perspective of one ol' the circularly-arranged straw carriers and agitators. Fig. 7 is a similar view of the grain guiding plate.

Referring to the drawings, 1 designates a threshing cylinder which is suitably mounted at one end of the main frame; 2 a series of walking rakes for carrying and agitating the straw, said rakes being horizont ally-arranged within the machine and connected at their front ends to a crank-shaft 3 by which they are given va constant reciprocation. Each rake is preferably composed of two spacedapart toothed bars 4 connected by spacedapart cross bars 5 through which the grain may fall. These rakes are diagonally-arranged within the machine, their discharge ends being extended toward one side thereof'. In conse uence no two of these rakes are of the same ength. On their 'under sides they ]ing approximately thc full length thereof. l T his drum, which is shown as of open-work formation, boing composed of suitablybraced wire-mesh, or perforated sheet-metal, has at its ends rings or flanges 12 which engage friction rolls 13 mounted on the frame.

lli designates a series of circularly-arranged carriers by which the straw is made 'to travel with the drum and during such travel it is agitated to remove the grain. .lhesc carriers comprise pivot-bars having tincs or heater arms projecting laterally therefrom. Each pivot-lair is hung in the ends of the drum, and its ends are cranked and carry rollers 15 which travel in stationary tracks 1G located within tho opposite ends of the drum. These tracks in rtheir bottom portions have each a series of cams or ridges 17 to eii'ect the constant vibration olI each carrier as its frictional rollers engage therewith. At the top cach track 16 is dipped or downwardly curved, as at 1S, to permit the several carriers to drop or open inwardly. T he straw as it is discharged from the walking' rakcs 2 falls upon the revolving carriers and as the straw travels therewith it is thoroughly agitated or shaken by thc rapid vibrations of the carriers when passing over the lowest point of travel. The straw is then carried upon the outside of a shield 19 and deposited on a shield or detlector 2() as the several carriers open inwardly. 'lhis shelf or del'lector is slightly inclined, and is wider at one end than at the other.

21 designates a. second series of walking rakcs which, like the first described series, is located within the dr u in and hence surrounded by the revolving series of carriers. These walking rake-s 21, however, dillcr from thi` walking rakesZ in that they are extended longitudinally through the machine. on straight lines, but on an incline so that the straw thereon will be discharged at the rear of the machine wnere it may be taken care of by ay pneumatic stacker, or other suitable means, not shown. The straw is further agitated to el'lect the separation of the grain by the action of the upper set of walking rakos, which latter are supported at their rear ends by pivoted bearings 21'lL and at their 'front ends by a crank-shaft 2lb. These rakes 2l in taking up the straw as it comes from de- Allector 20, and 'fieding the saine rearward beneath the latter, ellect the third turning thereof, the -first turning being accomplished by the transfer of the straw l'rom walking rakes 2 and the second by the deposit ci the straw on the detlector.

From the described arrangement it wiil be understood that the straw aiter leaving the threshing cylinder is iirst acted upon by the series of diagonally-arranged wallzing rakes and from them is taken up and inverted by the revolving carriers, which thoroughly beat or agitate the straw as it passes beneath the initially-acting walking ralres, is then carried up and again inverted and discharged upon the shelf or detiector 2O and is a third time inverted as it is taken up by the second series of walking rakes before being discharged 'from the machine. The thorough agitation and overturning oi' the stra f insures the separation ot' all the grain.

Beneath thenpper series of walking rakes is a vibrating pan 22 ipported at its front by hangers 23 while at its rear it is connected by arms 24 to two of the ralres. Se also beneath walking rakes 2 is a vibrating pan 25. All grain will fall onto a concaved bottom 26, and from this it is-removed by bars 27, arranged longitudinally, on the outside of the drum. is the grain clears the upper edge ofthe bottom it will fall against an otter plate or section 28 of the inclosing frame, and by guides 29 will be directed toward the rear half of a centrally-divided or two-part screen 30 mounted within a vibrating frame 31. "il'his vibrating frame carries the usual and ordinary sieves, and in close jrxtaposition thereto is arranged the grain-receiving trough 32, the trough 33 for screenings or white caps, and the chaff-receiving tron gh 34. At 35 l have shown a duplex fan for effecting the separation of the chart' ete. from the grain, and at 36 the fan for ejecting the chan", but asthese form no special part of my invention it is not necessary to describe them or the means for operating them.

The particular means for actuating the walking ralres and for revolving the drum and carriers maT be changed at pleasure, since it forms no part of my invention. have shown, however, a driven shaft 37 having a beveled gear connestion with a shaft 38 extended longitudinally ofthe machine at the top thereof for driving bands 39'which engage with the end rings of the drum. 1in practice 1 may use sprocket chains for this purpose. l have also shown the crank shafts 3 and 2lb or' the two series of walking rakes as being actuated by suitable belting extending from the operating shaft.

The advantages of my invention will be apparent to those skilled in the art to which it appertains. By effecting the thorough agitation and vibration of the straw, coupled with the turning of the latter over in its transit through the machine, 1 insure the removal of all grain from the straw. 1n fact the grain is so thoroughly removed by the time the straw is carried upwardly by the revolving carriers, after being acted upon by the vibrations of the latter and the iirst i series of walking rakes, that but comparatively little grain remains in the straw when it falls onto the upper series of walking rallies.

As is shown in ig. 6 the tines or beater arms 01" each of the revolving carriers may be covered by sheets 10 of v-,fire-mesh to more thoroughly insire the separation of the grain by the agitation of the carriers.
